"Introduction to Genetics: Packing Your Genetic Suitcase"
Bellwork:
Why do we look the way we do?
- Define genes (the basic units in cells that make organisms look the way they do) and discuss how we get them from our parents
- Pass out "Genetics Vocabulary" worksheet and define "genes" in our own words
- Students pack genetic suitcases ("Packing Your Genetic Suitcase" worksheet) with the genes they have and got from their parents ==> must include eye color, hair color, straight/bent pinky, can/can't curl tongue, free/attached earlobes, straight/peaked hairline, and any other examples students can think of
- Students share what they packed in their genetic suitcase ==> we all packed the same basic features but those things we packed had different traits
- Define "feature" and "trait"
Feature: The physical structures of an organism
Trait: The specific way that feature is expressed
- Students give an example of a feature and trait they have on their "Genetic Vocabulary" sheet (ex: feature is hair, trait is brown color)
